Took it this morning and passed! For anyone still waiting on the Euler invite, I never got mine either. What worked was logging in directly at https://anthropic-partners.skilljar.com with the shiftsmartai email, going to Certifications, and buying the exam there ($125). Pearson sent the scheduling email right after and I booked it on OnVUE. One tip if you're taking it online: run the OnVUE system test ahead of time. Mine kept failing until I force-closed Edge running in the background. What helped me most for studying was the official exam guide and the sample questions in it. A lot of the answers come down to picking the simplest fix that actually enforces the behaviour, rather than the most elaborate one. Big thanks to @Alice Bazdikian and @Anita Ortiz for all the support! 🥳 Good luck to everyone booking next week :)
